Research Interests
    Nanomaterials for environmental/sensing applications

    One crucial property of nanomaterials is its large active surface area compared to that of conventional size materials. Several phenomena in nature such as adsorption and catalysis rely on interaction at the material interfaces and the use of nanomaterials can help to amplify or to better utilize these interface effects. The focus here has been on utilization of magnetic nanoparticles in separation of contaminants/ active components in several systems such as in environmental remediation, biomedical system and in heterogeneous catalysis. Ability of these nanoparticles to bind specifically to the interested target and to be separated or concentrated magnetically can also be exploited in sensing applications. Optical detection based mainly in infrared and UV-Visible regions are also being developed.
